Description

Technical Field

[0001] This invention relates to the field of high-phosphorus waste treatment technology, and in particular to a high-phosphorus explosion-proof vortex incinerator and its usage method. Background Technology

[0002] The high-phosphorus explosion-proof vortex incinerator is an advanced technology specifically designed for treating waste containing high concentrations of phosphorus, widely used in fertilizers, pesticides, and metal surface treatment. Treating phosphorus compound waste is challenging because it easily produces toxic gases, such as phosphine, at high temperatures, potentially triggering explosions. The vortex incinerator utilizes the effect of rotating airflow to improve the mixing efficiency of waste and air, ensuring uniform combustion and avoiding localized overheating and explosion risks. Simultaneously, precise temperature control and exhaust gas treatment systems effectively reduce harmful gas emissions, ensuring environmental compliance. High-phosphorus waste requires appropriate pretreatment before entering the incinerator, and temperature must be strictly monitored and adjusted during incineration to prevent explosions. Furthermore, the vortex incinerator is equipped with advanced explosion protection measures, such as pressure relief valves and gas detection systems, ensuring operational safety. With continuous technological advancements, the vortex incinerator improves incineration efficiency and safety while better meeting the needs of industrial waste treatment and environmental protection.

[0003] However, in actual use of existing solutions, gas explosions can be caused by multiple factors, one of the most significant being incomplete or uneven combustion of waste. If waste is not completely burned during incineration, combustible gases (such as carbon monoxide and hydrocarbons) may accumulate inside the furnace. When these combustible gases mix with air, they can cause gas explosions if they encounter an ignition source or a localized high-temperature area. Furthermore, excessively rapid combustion in certain areas can lead to excessively high temperatures in those areas. This uneven combustion can cause temperature fluctuations within the furnace, affecting its stability and further exacerbating incomplete combustion.

[0004] Therefore, the present invention provides a high-phosphorus-content anti-explosion vortex incinerator and its usage method. Summary of the Invention

[0013] As a preferred technical solution of this application, an outer pipe is fixedly connected to the inner side of the first combustion chamber, and a uniformly distributed discharge pipe is opened on the outer wall of the outer pipe.

The discharge pipe is connected to the inner cavity of the first combustion chamber and the inner cavity between the outer pipe and the inner pipe.

[0014] As a preferred technical solution of this application, the air intake assembly includes a second delivery pipe, which is connected to the inner cavity between the outer pipe and the inner pipe. A second control valve is provided in the middle section of the second delivery pipe, and a catalyst storage tank is fixedly connected to the other end of the second delivery pipe. A support frame is fixedly connected to the bottom wall of the catalyst storage tank, and an oxygen cylinder is fixedly connected to the top wall of the support frame.

[0015] As a preferred technical solution of this application, the top wall of the screening box is provided with a sealing door.

[0016] A method for using a high-phosphorus-content anti-explosion vortex incinerator includes the following steps:

[0017] S1. The waste material is crushed by a crusher. The crushed waste material falls onto the top of the screen plate and is vibrated by a vibrating motor to screen the crushed waste material. The waste material is screened and graded through an area with three screen holes of different diameters at the top of the screen plate. Waste particles of different diameters fall into different hoppers and are transported out by an auger conveyor assembly.

[0018] S2. The second motor drives the second auger blades to rotate in the through holes opened inside the screening box. At the same time, the exhaust fan draws out the air and dust in the screening box through the filter screen and filters the dust, thereby reducing the dust content in the air inside the screening box and avoiding affecting subsequent incineration. The rotation of the second auger blades driven by the second motor pushes the dust filtered by the filter screen to the outside and cleans the surface of the filter screen.

[0019] S3. After entering the first combustion chamber, the waste is incinerated. During the process, gas sensors installed inside the first combustion chamber monitor key parameters such as gas composition, temperature, and pressure at the furnace and exhaust outlet. Harmful components in the exhaust gas are detected in real time. If any exceedance is detected, the system automatically controls the opening and closing of the first and second control valves, thereby controlling the oxygen and catalyst supplied to the first combustion chamber. Simultaneously, the system controls the air supply from the first and second air fans to both combustion chambers, thereby improving combustion efficiency and reducing the generation of harmful gases.

[0020] Compared with the prior art, the present invention provides a high-phosphorus-content anti-explosion vortex incinerator and its usage method, which has the following beneficial effects:

[0021] 1. The present invention discloses a high-phosphorus explosion-proof vortex incinerator and its usage method, wherein the waste is crushed by a crusher, and then the screen plate is vibrated by two vibrating motors to screen the crushed waste and divide it into three grades. The waste is then conveyed into the screw conveyor assembly through a hopper. This allows the raw materials to be graded according to particle size, avoiding uneven combustion caused by different sizes of the same batch of waste entering the incinerator. At the same time, reducing the size of the waste particles helps oxygen react more easily with the waste, thereby improving combustion efficiency, ensuring complete combustion of waste, reducing incomplete combustion and the generation of harmful gases, and reducing the probability of gas explosions.

[0022] 2. The high-phosphorus-content anti-explosion vortex incinerator and its usage method described in this invention, by setting up multiple incinerators, each corresponding to a particle size class, and incinerating them separately, can optimize combustion conditions. Temperature and oxygen levels can be adjusted for different particle sizes, thereby improving combustion efficiency. Smaller particles burn rapidly, while larger particles require more time; separate incineration ensures complete combustion of particles under optimal conditions. Secondly, separate treatment helps control the emission of high-phosphorus-content waste, preventing phosphorus from converting into harmful gases and reducing pollutant generation. Furthermore, separate incineration can optimize thermodynamic control, preventing temperature fluctuations from causing explosions or incomplete combustion, ensuring the safety and stability of the incineration process.

[0023] 3. The high-phosphorus explosion-proof vortex incinerator and its usage method described in this invention utilizes an exhaust fan to extract and filter dust generated during the screening process inside the screening box through a filter screen. Simultaneously, a second motor drives a second auger to clean and collect the dust filtered from the filter screen surface, thus cleaning the filter screen surface. This reduces pollutant emissions, improves air quality, ensures efficient operation of the filtration system, extends equipment lifespan, and lowers maintenance costs. Furthermore, this approach stabilizes the combustion process, reduces the risk of gas explosions, and enhances the incinerator's safety and overall operating efficiency.

[0024] 4. The high-phosphorus explosion-proof vortex incinerator and its usage method described in this invention uniformly delivers oxygen and catalyst to the first combustion chamber through the outer and inner pipes, respectively. This promotes complete combustion of fuel, ensures relatively complete combustion of high-phosphorus waste, improves overall combustion efficiency, reduces the generation of unburned substances, and the balanced oxygen supply effectively controls the temperature and airflow within the incinerator, preventing excessively high or low temperatures, thereby ensuring the stability of the combustion process and reducing the risk of gas explosions. Furthermore, in conjunction with a gas monitoring sensor, the opening and closing of the first delivery pipe and the second control valve can be controlled to regulate the flow rate of oxygen and catalyst, improving the automation and intelligence of the equipment.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0039] Reference Figure 1-11A high-phosphorus explosion-proof vortex incinerator includes a screening box 1. A crusher 11 is fixedly connected to the outer wall of the screening box 1. The crusher 11 first crushes the waste material. Three hoppers 26 are opened inside the screening box 1. A screening component is set inside the screening box 1. A screening plate 24 is set at the screening end of the screening component. The crushed waste is screened through the screening plate 24. A through hole is also opened inside the screening box 1. A dust filter cleaning component is set inside the through hole. A second auger blade 32 is set at the cleaning end of the dust filter cleaning component. An auger conveying component is set at the bottom of the hoppers 26. An incinerator component is set at the discharge end of the auger conveying component. An air inlet component is set inside the incinerator component. An outer pipe 6 is set at the air inlet end of the air inlet component.

[0040] The screening assembly includes a slider 2, which is slidably connected to a groove on the inner side of the screening box 1. A first spring 22 is fixedly connected to the bottom wall of the slider 2, and the other end of the first spring 22 is fixedly connected to the inner wall of the groove. A second spring 23 is fixedly connected to the top wall of the slider 2, and the other end of the second spring 23 is also fixedly connected to the inner wall of the groove. The slider 2 is supported by the second spring 23 and the first spring 22. A support rod 21 is also fixedly connected to the top wall of the slider 2, and a screening plate 24 is fixedly connected to the top of the support rod 21. Corresponding vibration motors 25 are fixedly connected to both sides of the bottom wall of the screening plate 24. The vibration motors 25 drive the screening plate 24 to vibrate, and at the same time, the screening plate 24 drives the slider 2 to slide between the first spring 22 and the second spring 23 through the support rod 21. The first spring 22 and the second spring 23 support the slider 2 and control the amplitude of the screening plate 24.

[0041] The screening plate 24 has three screening hole areas from one side to the other, and the three screening areas are opposite to the three hoppers 26. The screening plate 24 has three screening holes on its surface, and these three screening hole areas correspond to the opposite hoppers 26. The particle size screened from one side of the crusher 11 to the other side is from small to large.

[0042] The dust filtration and cleaning assembly includes a second motor 31, which is fixedly connected to one end of a through hole on the inner side of the screening box 1. The second motor 31 is fixedly fixed through the screening box 1. A second auger blade 32 is fixedly connected to the output end of the second motor 31. The second auger blade 32 is fixedly fixed through the second motor 31 and simultaneously drives the second auger blade 32 to rotate within the through hole. A uniformly distributed filter screen 33 is fixedly connected to the inner wall of the through hole on the inner side of the screening box 1. The filter screen 33 is fixed through the screening box 1. An exhaust fan 34 is fixedly connected to the outer side of the filter screen 33 and is fixedly connected to the screening box 1. The exhaust fan 34 extracts the dust generated during the screening process inside the screening box 1 through the filter screen 33. The combustion of high-phosphorus waste is prone to gas explosion. Excessive dust and accumulation may increase the system resistance and temperature fluctuations. Effective dust extraction and filtration can reduce equipment instability caused by dust accumulation, thereby reducing the risk of gas explosion and improving the safety of the incinerator.

[0043] A screen 3 is installed between the through hole on the inner side of the screening box 1 and the space where the screening plate 24 is located. The screen 3 separates the crushed waste from the through hole, thereby preventing the waste from entering the through hole through the screen 3 during the screening process.

[0044] The incinerator assembly includes a first combustion chamber 4, and a second combustion chamber 41 is fixedly connected to the outside of the first combustion chamber 4. The second combustion chamber 41 is supported by the first combustion chamber 4. Waste is incinerated in the first combustion chamber 4. The exhaust gas generated during the incineration process enters the second combustion chamber 41 for further incineration. A second air supply fan 45 is fixedly connected to the outside of the second combustion chamber 41. An exhaust gas treatment pipe 42 is fixedly connected to the outside of the second combustion chamber 41. The exhaust gas generated after incineration in the second combustion chamber 41 is discharged through the exhaust gas treatment pipe 42. A real-time monitoring system is introduced into the exhaust gas treatment pipe 42, and key parameters such as gas composition, temperature, and pressure at the exhaust gas outlet are monitored by installing gas sensors. The system performs real-time monitoring of harmful components in the exhaust gas, such as CO, NOx, and phosphides. If any exceedances are detected, the system automatically adjusts combustion conditions and airflow or activates exhaust gas treatment equipment to ensure emissions meet environmental standards. The first combustion chamber 4 has a door on its outer side that connects to the discharge end of the auger assembly. The auger assembly includes a conveying cylinder 27, a first motor 28, and first auger blades 29. The first motor 28 drives the first auger blades 29 to rotate within the conveying cylinder 27. Simultaneously, a feed hole is provided at the connection point between the conveying cylinder 27 and the hopper 26, allowing the screened waste material to enter the conveying cylinder 27 through the hopper 26 and the feed hole. Then, the first motor 28 drives the first auger blades 29 to rotate, thus conveying the waste material into the first combustion chamber 4. Multiple first air supply fans 44 are simultaneously installed on the outside of the first combustion chamber 4. The air supply fans 44 are arranged in a spiral direction to deliver air into the first combustion chamber 4. The air intake direction is biased towards the inner wall of the first combustion chamber 4, thereby forming a vortex and increasing the contact area between the air and the waste. A fly ash collection box 43 is fixedly connected to the outside of the first combustion chamber 4. The air intake end of the fly ash collection box 43 is connected to the inner cavity of the first combustion chamber 4. During the incineration process, the vortex will cause the waste to tumble in the first combustion chamber 4, thereby improving the incineration efficiency. At the same time, the fly ash generated during incineration is blown up. Since the fly ash itself has its own weight, the centrifugal force generated by the vortex will cause the fly ash to rotate outward. During the process, the fly ash is collected by the fly ash collection box 43.

[0045] An outer pipe 6 is fixedly connected to the inner side of the first combustion chamber 4. The outer wall of the outer pipe 6 has evenly distributed discharge pipes 61. An inner pipe 62 is fixedly connected to the inner side of the outer pipe 6, and the inner pipe 62 is fixed by the outer pipe 6. An evenly distributed air outlet pipe 63 is fixedly connected to the inner wall of the inner pipe 62, and the air outlet pipe 63 is fixed by the inner pipe 62. The two ends of the air outlet pipe 63 connect to the inner cavity of the first combustion chamber 4 and the inner cavity of the inner pipe 62, respectively. The raw material transported in the inner pipe 62 enters the first combustion chamber 4 through the air outlet pipe 63. The discharge pipe 61 connects the inner cavity of the first combustion chamber 4 and the inner cavity between the outer pipe 6 and the inner pipe 62. The raw material transported in the inner cavity between the outer pipe 6 and the inner pipe 62 is transported into the first combustion chamber 4 through the discharge pipe 61. Simultaneously, a screw conveyor is installed at the bottom of the first combustion chamber 4. The ash and slag generated during combustion are discharged outside the furnace through the screw conveyor and enter the ash and slag collection system.

[0046] The intake assembly includes a second delivery pipe 58, which communicates with the inner cavity between the outer pipe 6 and the inner pipe 62. A second control valve 59 is installed in the middle section of the second delivery pipe 58, and a catalyst storage tank 57 is fixedly connected to the other end of the second delivery pipe 58. A support frame 5 is fixedly connected to the bottom wall of the catalyst storage tank 57, and an oxygen cylinder 51 is fixedly connected to the top wall of the support frame 5. The support frame 5 simultaneously supports and fixes the oxygen cylinder 51 and the catalyst storage tank 57. A first delivery pipe 52 is fixedly connected to the outside of the oxygen cylinder 51, and a first control valve 53 is installed in the middle section of the first delivery pipe 52. The other end of the first control valve 53 is fixedly connected to the second delivery pipe 59. A first connecting hose 54 is fixedly connected to the oxygen cylinder 51, and a filter valve 55 is fixedly connected to the other end of the first connecting hose 54. The oxygen cylinder 51 and the filter valve 55 are connected through the first delivery pipe 52, the first control valve 53, and the first connecting hose 54. When the oxygen in the oxygen cylinder 51 flows through the filter valve 55, it is filtered to ensure the purity of the oxygen. A second connecting hose 56 is fixedly connected to the other side of the filter valve 55. The second connecting hose 56 is connected to the inner tube 62, and the filter valve 55 and the inner tube 62 are connected through the second connecting hose 56. The filtered oxygen enters the oxygen cylinder 51 through the second connecting hose 56. The gas enters the first combustion chamber 4 evenly through the inner pipe 62 and the outlet pipe 63. Oxygen acts as a combustion aid, while the catalysts include ammonia (NH3): Ammonia can act as a reducing agent in the catalytic denitrification process under certain high-temperature conditions. Ammonia reacts with nitrogen oxides (NOx) to form harmless nitrogen (N2) and water, thereby effectively reducing nitrogen oxide emissions and improving the environmental performance of the incinerator; Ozone (O3): As a strong oxidant, ozone can help decompose harmful substances in certain high-temperature incineration processes, especially in the process of exhaust gas purification, where ozone can effectively oxidize and remove volatile organic compounds (VOCs). This solid-gas mixed catalyst, which combines oxidants (OCs) and other hazardous substances with solid catalysts such as alumina (Al2O3) and copper-based catalysts (CuO), accelerates the oxidation of phosphorus compounds in waste, improves combustion efficiency, reduces incomplete combustion and the generation of harmful gases, further accelerates the reaction rate, provides a uniform gas supply, enhances the stability of airflow within the furnace, avoids temperature fluctuations and gas explosions, and ensures the safety of the combustion process. Furthermore, the use of this solid-gas mixed catalyst can effectively decompose harmful substances such as phosphates and nitrogen oxides, reducing environmental pollution and improving waste gas purification efficiency. Simultaneously, this catalyst combination optimizes heat transfer, promotes waste tumbling and uniform combustion, improves furnace temperature uniformity, reduces catalyst consumption, and extends its service life, thereby improving the overall system's economic efficiency.

[0047] The top wall of the screening box 1 is equipped with a sealing door 12. The top of the screening box 1 can be opened through the sealing door 12 to observe the screening situation inside and facilitate subsequent maintenance.

[0048] A method for using a high-phosphorus-content anti-explosion vortex incinerator includes the following steps:

[0049] S1. The waste material is crushed by the crusher 11. The crushed waste material falls into the top of the screen plate 24 and is vibrated by the vibrating motor 25 to screen the crushed waste material. The waste material is screened and graded by the area with three screen holes of different diameters at the top of the screen plate 24. The waste material particles of different diameters fall into different hoppers 26 and are conveyed out by the auger conveyor assembly.

[0050] S2. The second motor 31 drives the second auger blade 32 to rotate in the through hole on the inside of the screening box 1. At the same time, the exhaust fan 34 draws out the air and dust in the screening box 1 through the filter screen 33 and filters the dust through the filter screen 33, thereby reducing the dust content in the air inside the screening box 1 and avoiding affecting subsequent incineration. The rotation of the second auger blade 32 driven by the second motor 31 pushes the dust filtered by the filter screen 33 to the outside and cleans the surface of the filter screen 33.

[0051] S3. After entering the first combustion chamber 4, the waste is incinerated. During the process, gas sensors installed inside the first combustion chamber 4 monitor key parameters such as gas composition, temperature, and pressure at the furnace and exhaust outlet. Harmful components in the exhaust gas, such as CO, NOx, and phosphides, are detected in real time. If any exceedance is detected, the system automatically controls the opening and closing of the first control valve 53 and the second control valve 59, thereby controlling the oxygen and catalyst supplied to the first combustion chamber 4. At the same time, the system controls the amount of air supplied by the first air supply fan 44 and the second air supply fan 45 to the first combustion chamber 4 and the second combustion chamber 41, thereby improving combustion efficiency and reducing the generation of harmful gases.
